Normal torque for a screw driver is about 14 in/lbs to tighten a screw. Many of my torque wrenches won't even go that low. Most start at 30 in/lb and that ain't much. The one I use is a 0 to 600 in/lb dial type but I'm accustomed to how much a pinion shaft rolling torque should be. 20 in/lb would be more of a break away torque to me with a rolling torque around 11 or 12 in/lb. You want them tight enough for long term wear but you don't want them so tight you can't turn them by hand.Used bearings need less rolling torque. New bearings shouldn't go over max. I'd figure around 18 in/lb would be max for me. This is using light oil for lubricant.
